Komodo Dragon 2.6.1 released

[lkaufman]

Something broke it in the Fritz 17 gui. The "UCI Elo" option doesn't display in the engine parameters screen like it does in version 2.6.
I registered 2.6.1 in Cute Chess and I can see the option there but not in Fritz 17.

Yes, this is the issue we have had to deal with. In the ChessBase/Fritz GUIs the option showed up in 2.6 as an engine param, but not in "training mode". In response to many requests, we switched it in 2.6.1 so that it does show up in training mode, but not as a UCI param. So for running engine matches, it seems that the choice is either to revert to 2.6 (which is within 2 elo so that's ok) or to use Cute Chess or some other GUI.

Please let it be like this, if you should let it be visible in Fritz do it like ShashChess with extra options to show up in Fritz.
Now it is working in Hiarcs like a dream with keeping track of your rating against Dragon. There is a little hack to get it to work though. Hiarcs disregard the hole UCI_Elo when min start at 0. By the answer I got it seems they don't want to fix it (what is UCI_elo=0 ?). I don't want to argue with them, I'm sure they know of Mr. Elo and his paper that say that the endpoint are floating.
If you get question/bugreport of this, the hack is this (running from commandline after Dragon are installed):

Code: Select all

reg add "HKEY_CURRENT_USER\SOFTWARE\hiarcs\ChessExplorerPro\Engines\1" /v "EloLimit" /t REG_SZ /d "1-3500" /f

The number 1 (in Engines\1) is the number of the engine counted from the top with the top being 0. So 1 says that Dragon are the second engine.

By the way I am testing to find suitable engines to run againt Dragon in the range 1000-2000 Elo. I report back when I have found enough to get good result. I run 1+1 matches since I'm not interested in the elo of the other engines, just that they are stable in 1+1 matches. And Dragon play the same in 1+1 as it do in 15+10.

Edit:
Forgot that there also are something called Mac, I haven't seen them since they had only one button on the mouse. I think they have something called application support folder where it probably exist.

Ok, thank you. For games that I am playing in what happens if I set the elo to something like 1800 but I don't check the limitstrength option?

I believe that if you don't check limitstrength, it will ignore the elo setting and play at full strength.

Also under Arena 3.5.1 under Levels you can set Limit Playing Strength to ELO, and that is all, if you are using the Latest Komodo Dragon 2.6.1

Ok 2.6.1 introduced a UCI_Elo bug for some GUI's which ignore UCI_Elo when it's set to 0 which is the default setting?!

Please fix it.

You are doing it wrong, to set the engine to default settings, you have to click Engines and click again where it say Engine1 or Engine2 where Komodo Dragon is located and then click configure and click where it say Reset to defaults and click Okay under Arena 3.5.1.

Note: Under other GUI's you do NOT set Komodo Dragon 2.6.1 to default setting where the UCI_Elo is located either, and if that was the case the closest rating to Komodo Dragon 2.6.1 under UCI_Elo is 3500 NOT 0 anyway

Maybe I don't understand the problem. If setting elo to 0 really just sets it to default 3500 (which is full strength), it just means that the range of elos that work is 1 to 3500, with 0 meaning "off". That seems perfectly fine if that's the case, just set elo to 1 for minimum strength, which would only be appropriate if you are having it play a six year old kid who just learned the moves of the pieces (roughly speaking). If I misunderstand the problem, please explain.

But if Komodo is trying to emulate FIDE rated players, it should start with a minimum of 1000, since the lowest FIDE rating that can be achieved is 1000, because of the rating floor in FIDE's rating system, 1000 is the lowest attainable rating. A handful of players have this rating, most of them kids and the Maximum 2950 which I doubt that Carlsen ever will achieve in his lifetime

Yes, FIDE 1000 is the minimum, but it is not supposed to mean beginner level. Chess.com ratings are in general reasonably close to FIDE ratings (below GM level anyway), give or take a couple hundred elo, but the AVERAGE rating there is something like 1200, with the minimum close to zero. My guess is that the average adult who admits to knowing how to play chess would not be able to earn a FIDE rating of 1000 given the appropriate opportunity. So just consider 1000 and above as intended to match FIDE, and ratings below that more or less comparable to chess.com or perhaps USCF scholastic ratings. At the high end, remember these are Rapid ratings, so assuming that 2850 is correct for Rapid, Carlsen would need to set the Elo to something like 3000 for an even challenge at Classical chess, and if he wants to play a somewhat stronger opponent at classical against whom he would still have good drawing chances when playing White, a setting of 3200 might be appropriate. Or to simulate how Carlsen would play at one move per day correspondence chess, maybe 3400 or so is about right. So there are valid reasons for the entire range of Elo settings, although for most of our customers 1000 to 2700 would be sufficient.
